Dear team,

After update to the latest version (2.1.1) I’ve got the following error at Eclipse startup time:

Synchronize Gradle projects with workspace failed due to an unexpected error.
loader constraint violation: when resolving method "com.gradleware.tooling.toolingmodel.repository.internal.DefaultOmniEclipseProject.getAll()Lcom/google/common/collect/ImmutableList;" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, org/eclipse/buildship/core/workspace/internal/DefaultModelProvider, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for the method's defining class, com/gradleware/tooling/toolingmodel/repository/internal/DefaultOmniEclipseProject, have different Class objects for the type com/google/common/collect/ImmutableList used in the signature

Can you try using the latest Buildship 2.1.2 snapshot? It should contain a fix for all those classpath issues.
